11.10.4 CLIM Command Line Interaction Style

One interaction style supported by CLIM is the
command line style
of interaction provided on most conventional operating systems. A command prompt is displayed in the application's
:interactor
pane. The user enters a command by typing its command line name followed by its arguments. What the user types (or enters via the pointer) is echoed to the interactor window. When the user has finished typing the command, it is executed.

In CLIM, this interaction style is augmented by the
input editing
facility, which allows the user to correct typing mistakes, and by the prompting and help facilities, which provide a description of the command and the expected arguments (see Chapter 16, Input Editing and Completion Facilities). Command entry is also facilitated by the presentation substrate, which allows the input of objects matching the input context, both for command names and command arguments.
